1 claim. (ci. 11a-1) This invention relates to trimmings, edgings, andlike materials of the type known as fagoting and commonly used byworkersin the needlecraft arts for the adornment of articles of wear- 5 ingapparel and stitched household draperies,

linens, etc.

The invention has for an object to provide an ornamental trimming orfagoting strip which may be readily made in any desired length in l avariety of patterns by an unskilled person with the aid of a simple handforming frame used in conjunction with a household sewing machine.

Another object of the invention is to provide a trimming strip ofopenwork formation which l may. without distortion, be readily andaccurately guided to the needle of a sewing machine in the attachment ofthe trimming strip to fabric material, either as a surfaceornamentation, as an edging, or as an insertion.

With the above and other objects in view, as will hereinafter appear,the invention comprises the devices, combinations and arrangements ofparts hereinafter set forth and illustrated in the accompanying drawingsof a preferred embodi- 25 ment of the invention, from which the severalfeatures of the invention and the advantages attained thereby will bereadily understood by those skilled in the art.

This application is a division of applicants 30 copendlng applicationSerial No. 713,843; filed March 3, 1934.

It is to be understood that the term strand" is used herein in a broadsense including any narrow strip-like material, such as tape, ribbon,

35 cord, thread or yarn, of woven, knitted, braided or twisted texture.

According to the preferred embodiment of the invention illustrated,there is provided a trimming strip forming frame or forked membercomprising an end-member or handle I having a long centrally projectingprong or tongue 2 terminating at its free end in a T-head 3. Fulcrumedon the pivot-pins 4 which are fixed to the handle I are the side-bars orprongs 5a, 5'0 each of which has the cross-'sectional form of anangle-bar having a flat base-portion 5 and an upstanding toothed portion5 at an acute angle to the baseportion, as shown in Fig. 4. The toothedupstanding portions 5 of the side-bars are spaced apart and each isspaced from the intermediate tongue 2 to provide narrow stitch-receivinggaps 6. There is pivoted at l to the free end of the side-bar 5a, adistance piece 8 of U-shaped crosssection having a channel 9 whichembraces or receives the ends ofthe side-bars, as well as the T-head ofthe tongue 2. The tip end I0 of the side-bar 5b projects through a holeII in the distance piece 8 and is thereby held in contact with one sideof the T-head 3y which latter is held in contact with the otherside-bar, as shown in Fig. 1. The Width of the T-head 3 is such thatwhen the distance piece 8 is closed, the tooth-rows of the side-bars arein parallelism. The distance piece 8 may be formed with one or moreadditional holes I2 to receive the tip-end Ill of the side-bar 5b whenit is desired to adjust the sidebars to angular or tapered relationshipwith oneanother, as shown in Fig. 2.

There is secured in fiat superposed relation upon the handle I, by theriveted Shanks of the pivot-pins -4, a leaf-spring I3 which is provided55 with rib-forming-strand-positioning slots I4 each in line with arespective stitch-receiving gap 6, Fig. 1. The distance piece 3 also hasrib-forming-strand-positioning notches I5 each cut in line with arespective one of the gaps 6. The distance piece l may be'furtherprovided with a notch I6 for the starting end of thetrimming-base-forming-strand I1, Fig. l and with one or more additionalnotches I9, Fig. 2, for one of the rib-forming strands I9.

Referring particularly to Fig. 6, it will be seen that the upstandingportions 5" of the side-bars are provided at equidlstant intervals withvertical slots 2II to form the teeth 2I the upper ends of which haveslightly beveled corners 22; the teeth 2i being substantiallyrectangular in form but without sharp corners or edges. 'I'he iirst fewteeth 2|' at the starting end of the frame, remote from the handle I,have their upper ends rounded on more than the remaining teeth 2| tomore easily receive the end-loops of a previously formed and stitchedlength of trimming strip for continuation of the manufacture of thetrimming strip to any desired length. The slots 20 extend substantiallyall the way down to the base portions 5' of the respective side-bars, sothat the trimming base strand I1 will, when looped upon the teeth of theframe, lie substantially in contact with the intermediate tongue 2. Itwill also be noticed that the flat base-portions 5 of the sidebars liein a common plane with the intermediate tongue 2 so that both theside-bars and tongue may rest iiat upon the cloth-plate of an ordinarysewing machine with which the device is intended to be used.

The sewing machine may be of the usual family or domestic type havingthe needle-bar 23 carrying the needle 24 which reciprocates verticallythrough the needle-hole 25 in the throat-plate 26. The machine has theusual flat bed or cloth-plate 21 and four-motion feed-dog 28 whichoperates through the usual feed-dog slots in the throatplate 26.

For use with the present trimming strip-forming frame, the usualspring-pressed presser-bar 29 of the sewing machine is preferably fittedwith a special presser-foot 30 having a flat sole-plate 3i and upturnedtoe 32. The sole-plate 3| is provided in its longitudinal center linewith a needle-hole 33 and on each side of its longitudinal center linewith a guide slot 34 for the upturned toothed portions 5" of one or theother of the side-bars of the trimming strip forming frame, there beingbetween the slots 34 a narrow central bar 35 which is provided in itsunder face with an inverted V-shaped groove 36 adapted to automaticallyguide the rib-forming strands I9, one at a time, to the needle so thatthe latter will stitch through and longitudinally of such strands. Theslots 34 in the presser-foot are so spaced laterally of the needle-hole33 that the rib-forming strands I9 will be guided longitudinally abovethe respective stitch-receiving gaps 6 in the forming frame.

To use the device for making a trimming strip with parallel edge lines,the frame is adjusted with its side-bars 5, 5b in parallel relation, asshown in Figs. 1 and 7. A trimming base strand I1 of material is thenknotted at its starting end and engaged in the starting notch I6 in thedistance piece 3 remote from the handle I. The strand I1 is then loopedback and forth by hand around the teeth of the side-bars andprogressively lengthwise of the latter to form the desired pattern. Thesubstantially rectangular form of the teeth 2I and the inclination ofthe teeth of each row away from the teeth of the other row,

-are of great assistance to the'operator in the hand-looping operation,as the loops may be formed upon and close to the upper ends of the teethand readily slide down to the bases of the teeth. The rib-formingstrands I9 are next placed in the notches I5 of the distance piece I andstretched lengthwise of the frame and slipped into the notches I4 of thespring I3 so as to overlie the legs of the loops of the base strand I1.'I'he rib-forming strands I 9 should be initially cut into lengths atleast equaling the length of the trimming strip desired to be made.which may be many times the length of the forming frame. The same ordifferent strands or cords may be used for the base and rib-formingstrands. The side-bars 5a, 5b are 'preferably stiffened, to resistbending or deformation under the cross-strains of the looped base strandI1, by having their fiat base-portions 5 widened beam-fashion centrallyof the lengths of the side-bars, as shown in Figs.' 1 and 2. l

When the frame has been wound as directed it is presented to a sewingmachine fitted with the presser-foot 30 and a line of stitches is passedthrough one rib-forming strand to secure the latter to the legs of thebase-strand loops. The stitching thread or threads are then cut and asecond line of stitching is passed through the other rib-forming strandto secure it to the legs of the base-strand loops in parallelism withthe first rib-forming strand. After both rib-forming strands have beenstitched to the looped base strand the frame is removed from themachine. and the stitched length of finished trimming is stripped fromthe teeth of the frame.

To assist in the stripping operation there may be provided a stripper31, Figs. 11, 12 and 13, made of two pieces of sheet-metal rivetedtogether at 38 and having lower and upper offset portions 39, 40 spacedapart to form a passageway 4I, Fig. 12, for the base-portion 5', of theside-bar 5b. The offset portions 39, 40 of the stripper have spacedupstanding lips 42, 43, respectively, forming a passageway for theupstanding toothed portion 5" of the side-bar 5b. Each of the lips 42,43 has an inclined edge 44 which cams the loops of the trimming stripupwardly, Fig. 1l, and dislodges them from the teeth of the side-bar 5b.The trimming strip may then be readily removed from the teeth of theother side-bar 5*. It is of course understood that the starting ends ofthe strands in the positioning notches of the piece I must be severedand the distance piece 9 opened before the stripper is applied to theside-bar 5b. 'I'he inner lip 42 of the stripper should preferably fitrather closely against the toothed upstanding portion 5" of the frameside-bar. so as to hold the outer upstanding lip 43 of the stripperclosely thereagainst in order that the inclined edge 44 of the outer lipmay engage and lift the ends of the loops of the trimming strip. It maybe desirable to provide the stripper with a spring tongue 45, Fig. 14,to resiliently engage the inner face of the toothed upstanding portion5" of the frame side-bar 5b through an opening 46 in the inner lip 42.

After the stitched portion of the trimming strip is removed from theframe, the last few loops stitched may be easily applied by hand, aidedby the pointed tongue 41 of the stripper, to the specially roundedend-teeth 2|' adjacent the distance piece 9, which is then closed to theposition shown in Fig. 1. The hand-looping of the base strand l1 is thencontinued to again fill the frame, after which the rib-forming strandsare drawn taut and slipped into the positioning notches Il and under thespring I3. The stitching is again resumed at the points where it waspreviously stopped and continued to the handle end of the frame. Thereis no danger that the stitching will be carried too far since one or theother of the upstanding pivot-pins Il will engage the upturned toe $2 ofthe presser-foot and arrest the feed of the frame before the needlereaches the end of the respective stitchingreceiving gap 8 in the frame.The stripping, looping and stitching operations may be repeated untilthe trimming strip attains the desired length.

It will be observed in Fig. 8 that the rising feeddog 28 engages theintermediate tongue 2 of the frame and lifts the -latter under thedownward yielding pressure of the spring-pressed presserfoot 30. It isfound in practice that the frictional engagement of the feed-.dog teethwith the under side of the tongue 2 'exceeds that of the loopedbase-strand Il vwith the under face of the presserfoot 30, so that thefeed-dog effectively feeds the loaded frame through and under thepresser-foot. Of course, the tongue 2 may, if necessary, be sand-blastedor otherwise roughened on its under face to increase the grip of thefeed-dog thereagainst. To make a tapered trimming strip, the frame isset up with the side-bars 5*, 5b inclined to one another, as shown inFig. 2. The trimming base strand Il is wound or looped around the teethof the side-bars in any desired pattern and the ribforming strands I!are stretched longitudinally of the respective side-bars between thenotches I5, I8 and slots il in the spring Il. The tongue 2 is thenshifted into parallelism with the side-bar i and one intermediaterib-forming strand Il is stitched to position across the legs of thebase strand loops. When the stitching of the first ribforming strand iscompleted, the side-bars are swung from full to dotted line position,Fig. 2, to shift the other side-bar i* into parallelism with the tongue2. 'I'he stitching of the second ribforming strand to the loopedbase-strand is then proceeded with. A

A great variety of trimmings may be produced by use of the presentdevice. In Fig. 15 there is illustrated the ladder" type of trimminghaving spaced parallel cross-bars 4B. Fig. 16 illustrates the closelyformed figure 8 type of parallel trimming with the angularly related orzigzag cross-bars 49. Fig. 17 shows an open form of figure 8 taperedtrimming. The parallel type of trimming oi' Fig. 18 is formed by usingan additional base-strand I1 which is looped onto the frame so that thelegs of the loops cross the legs of the loops of the base-strand I'I toform a series of Xs between the rib-forming strands II.

Any of the trimming strips according to the invention may be readily andaccurately applied as an edging to a body-fabric by merely superposingthe trimming strip upon a body fabric, and presenting the two to thesewing machine, as shown in Figs. 22 and 23, using the specialpresserfoot 30 to automatically guide one of the rib-forming strands ofthe trimming to the needle which sews the trimming to the body-fabric Ilwith a line of stitches il. The body-fabric Il is then folded around theline of stitches Si to the position shown in Fig. 24 and pressed toposition or additionally stitched by a line of stitches l2. Fig. 19illustrates a face view of the edged body-fabric of Fig. 24. Obviouslyby repeating the operation and using an additional piece of body-fabricIl' the trimming strip may be applied as an insertion. This effect isshown in Fig. 20 in simulation of zigzag cross-bar hemstitching, and inFlg. 21 in simulation of parallel cross-bar hemstitching. Inasmuch asthe trimming strip may be initially formed with strictly parallelrib-forming strands I8, and inasmuch as such strands are used to guidethe subsequently formed lines of stitching 5I and 52 used to attach thetrimming strip as an edging or as an insertion, it follows that a hithdegree of accuracy is readily attained in making insertions of uniformwidth or in applying edgings with uniformity.

variously colored threads, cords, twists. yarns and the like andcombinations of the same may be used in forming the base of thetrimming. The rib-forming strands may be of any suitable cylindricalcord-like material having sumcient size or thickness and body to beautomatically.

guided by cooperation with a grooved guiding element of a sewingmachine.

So far as I am aware. I am the first to provide an open-work trimmingstrip and means for chine guiding element to control the position of asubsequent line of sewing machine stitches in the attachment of thetrimming to a body-fabric.

The invention is not to be understood as limited to the specific formsand arrangements of parts or to the details of construction shown anddescribed as such forms, arrangements and details Having thus set forththe nature of the 'in-vention, what I claim herein is:-

A sewed trimming strip comprising, an ornamental base-strand of materiallooped back-andforth widthwise of the strip and progressively lengthwise`oi! the strip. a pair of cylindrical ribforming strands of materialdisposed wholly on one outer face of the strip and extendingstraightaway lengthwise of the strip across the legs of the base-strandloops wholly within the ends of the loops, and lines of sewingmachinestitches penetrating the respective rib-forming strands and securing therib-forming strands solely to the looped base-strand. said rib-formingstrands having sufficient thickness and body for subsequent cooperativeengagement with a grooved sewing mafabric material.
